MACHINE FOR ATTACHING HEELS.

T all wbnmii may concern:

Be it known that 1, WILLIAM R. BARCLAY, a citizen ofthe United States ofAmerica, and JosErI-I (,ToULDBoURN, a subject of the King of England,residing at Leicester, in the county of Leicester, England, haveinvented certain Improvements in Machines for Attaching Heels, of whichthe following description, in connection with the accompanying drawings,is aspecification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to improvements in machines for attaching heels,heel-lifts, or heel-tips with fillers to the heels of boots and shoesand if desired inserting slugs therein, its main object being to enabletoplifts or metal heel-tips with fillers to be attached to the heel by asecondary set of nails after the heel has been attached to the boot orshoe by a primary set of nails which may have been driven from theexterior of the boot. Further a machine according to this invention maybe used to attach Louis or like heels having a minimum cross-section ofconsiderable less area than the lifts adjacent to the heel-seat. In suchcases the heels may be separated into two layers or sections, and thelarger heel-seat layer be first attached by a set of nails extendingover an area greater than the minimum cross-sectional area of the secondlayer, which is attached in its turn by a second set of nails drivenwithin the space occupied by the nails used to attach the first orlarger heel-layer. Also a machine according to this invention may beused to drive slugs while stamping or blind-nailing a top-lift 'on tothe projecting heads of the primary attaching nails previously inserted.

Certain features of this invention may be combined with and used as anattachment to heeling machines of the class described in Letters Patentof the United States No. 694,656, granted March 4, 1902, to B. 'F. Mayo.

According to this invention a movable frame is provided carrying twocomplete sets of vertically-sliding nail drivers below correspondingnail-holding blocks, one set to be used for the heel-attaching nails,and the other for the tip and filler nails or toplift slugs, the driversof'both sets being parallel to each other. This frame is arrangedSpecification of Letters Patent.

Application filed September 8, 1904.

Patented Dec. 12, 1911. Serial No. 223,795.

This frame is preferably power-actuated by mechanism which correlatesthe movement of the frame with that of the plunger, to superimpose thesets of drivers alternately over the reciprocating nail-driving plunger;or it may be manually-operated for this purpose. Means may be arrangedon or in connection with the frame to hold the heel and the tip andfiller, or top-lift in position over their respective nail-holdingblocks and drivers. Two sets of nail-assorting mechanisms may beprovided, one on each side of the machine, one to load theheel-attaching nails, and the other the heel-tip and fillerattachingnails, or slugs, if it be desired to spank on and slug a top-lift inplace of the tip and filler. These mechanisms may be of knownconstruction and operated in a known manner. A pivoted cover-plate maybe provided which can be swung over the heel-tip and filler, after thesame is in position over its nail-holder, to prevent the vibrationengendered by the movement of the movable frame jerking the nails up outof the nail-holder through the holes in the heel-tip, and the nailsbeing trapped against the edge of the heel as the frame is swung over. Afixed stop on the machine engages the said cover-plate so that the samedoes not move under the heel, but is kept back swinging on its pivot asthe tip moves under the heel. Where a top-lift is to be spanked onto theprotruding heads of heel-attaching nails the pressure necessary to forcethe toplift on to them is applied to the lift by the movable frame inthe final portion of its rise with the plunger. If desired, slugs may bedriven into such a spanked-on lift by the drivers previously referred toas allotted to the nails for nailing on tips and fillers or top-lifts.

When this invention 1s used in the old machines of said Letters PatentNo. 694,656 the heel and top-lift carrying swing frame or plate thereofis retained and used to hold the heel, but is prevented from swinging,

. rendered inoperative.

the top-lift carrier of the said plate not being employed when it isdesired to attach to the heel a tip and filler or a top-lift with slugs.

Like letters of reference indicate like parts in all the figures.

With reference first to Figs. 1 to 9:

A is the main frame of the machine, comprising an upward extension orpillar curved over to the front of the machine at the top to form anoverhanging portion to sustain the jack, which may be of any suitableknown construction; preferably, as shown, the jack B is pivoted on to ascrew-threaded pin B working in an internally threaded sleeve B arrangedto rotate but not to have longitudinal movement in a bearing in theoverhanging portion of the frame. A hand-wheel B is provided to rotatethe sleeve. The jack may thus be swung to conveniently place a shoethereon or remove the same, and may be vertically adjusted to enable themachine to operate on heels of varying thickness. Below the jack and inline therewith is a horizontal taiole or head H, having a downwardextension H capable of vertical movement, but not of horizontalmovement, in a bearing formed in a projection A from the main frame A.The extensionH is hollow to receive a naildriver plunger J which extendsabove the table H through a hole in the same; the top of the plunger ispreferably provided with v a grooved head J, screwed or otherwisesecured thereon, and adapted to engage as a working fit in a slot ineither a heel-tip drivers-actuating slide L or a. heel driversactuatingslide M, as hereinafter described. The hollow portion of the extension His greater in cross-section than. the hole in the table H through whichthe plunger passes, a shoulder being thus formed which engages one endof a spiral spring J which surrounds the upper part of the plungerwithin the hollow of the extension. The other end of the spring engagesa shoulder on the plunger formed by an increase in diameter in the lowerportion of the plunger as shown in Fig. l. Preferably the plunger isactuated so as to make two strokes to one revolution of its drivingshaft and this may be conveniently done by means of a toggle J 2actuated by a crank J (see particularly Figs. 3 and 4), on a shaft J 4carried in bearings in the back of the frame A, the center joint of saidtoggle being connected to the crank by a connecting rod J 5 and thethrow of the crank being proportioned to operate the toggle beyond itsdead center on each side, so that one revolution of the shaft J 4imparts two vertical reciprocatlons to the plunger. On one end of theshaft J is a gear-wheel J 6 which is driven by a secondgear-wheel J 7011 one end of the main driving shaft A, carried in bearings in themachine frame above the shaft J The shaft A is actuated by a pulley Adriven by a belt from any convenient source of power.

Resting on the table H is a movable frame K, shown detached in Figs. 5and 6. The frame is shaped in plan substantially like a sector, fixed atits center on to the top of a short vertical rock-shaft K, which passesdown through the table H and is held in bearings in the projection A ofthe machine frame, so as to be both rotatable and movable endwisetherein. The front of the frame contains two vertical rectangularrecesses K K each extending throughout the whole height of said frame,placed side by side and similarly located with relation to the shaft Kso that partial rotation of the shaft K in either direction will causeone recess to occupy the position previously occupied by the other. Thelower portion of each recess K K is provided with vertical guide ways Kin which work nail-drivers actuating-slides, L M respectively, andnaildrivers-blocks, L M respectively. Each nail-drivers-block rests onthe top of its actuating-slide so as to be raised with the latter, andis constrained to follow its downward movement by ofi'-sets L M formedon upward side extensions of the slide, which oifsets prevent movementof the block away from its slide in an upward direction while allowingthe block to be readily removed from the frame. The drivers N have theirlower ends secured in any convenient mannor in the upper surface of theblocks L M, while their upper ends just enter the lower end of nailcavities L M formed in two nail holders L M carried respectively in theupper portion of the recesses K K and held from vertical movement in theframe K by horizontal bearings, L M respectively, engaged in grooves inthe recess wals. In the bottom of each driver-actuating slide L, M is acurved slot 0, the curves forming the sides of the slot-s being arcs ofwhich the pivotal shaft K of the movable frame is the center. Each slotopens through the side of its slide adjacent to the central line of theframe into a hole in the triangular portion of the frame lying betweenthe recesses K K thus forming a continuous path from the middle of oneslide to the middle of the other. The slots are. shaped in cross-sectionto form a working fit with the head J of the plunger J before described,which is received in them so that the plunger J may be brought, asdesired, within either of the driver-actuating slides L or M by rockingthe shaft K, which, as before described, forms the pivot of the movableframe K. A nail-holder and a nail-driversblock are shown detached inFig. 15 and an actuating slide in Fig. 16 of the drawings. Cover platesK may be bolted over the faces of the frame in which the recesses aresitauted, but these are preferably cut away in front of thenail-driver-blocks, drivers, and nailholders, allowing these parts to bereadily changed to suit varying sizes of heels.

The following is a convenientmeans for rocking the shaft K. The boss Kof an arm K (see Figs. 1 and 4) is spindled on to the shaft K so thatthe two will rotate togther, but the boss is held from endwise orvertical movement in a slot in the projection A of the machine frame, asshown in Fig. 1, while the shaft K, as before said, is free for suchmovement. A second vertical rocking shaft K carried in brackets A on themachine frame, has fixed on its upper end a short arm K, the free end ofwhich is connected by a link K with the free end of the arm K The lowerend of the second rockshaft K carries a pinion K which meshes with teethon a horizontal bar K adapted to slide in guide ways on the machineframe. On one end of the bar K is fixed a roller K engaged with a camgroove 1 14 on the face of a disk K fixed on the shaft J Convenientlyfor compactness of construction this disk may form, as shown in thedrawings, one arm of the crank J above described as operating theplunger.

An alternative construction for rocking the shaft K is shown in Figs. 8and 9. In this construction the vertical shaft- K is shown extendingupward instead of downward as above described, and, in place of thepinion K, is provided. with a worm-wheel K which meshes with and isdriven by a worm K carried on a shaft K rotatably carried in bearings onthe machine frame, the wheel K and worm I 21 being so proportioned thatfour complete revolutions of the worm K impart one complete revolutionto the shaft K On one end of the shaft 1' is a loose pulley Kcontinually rotated at high speed by a convenient source of power, thepulley being connected to the shaft K to operate the same at intervalsby a clutch P The clutch may be of a well-known type which permits onerevolution to be imparted to the shaft and then automatically stops andneed not be particularly described for the purposes of thisspecification. he clutch is put into action by a cam groove K on a diskK carried on the shaft J and which, as in the first-describedconstruction, may constitute one arm of the plunger-operating crank JThe clutch is operatively connected. with the cam groove 1 25 by meansof a roll K lever K and connect-ing rod K, the cam groove being shapedto put the clutch into operation and rotate the shaft K so as to givesimilarly timed movements and periods of rest to the movable frame K asin the previous construction.

The heel and the tip and filler or the top lift may be retained overtheir respective nail or slug holders by means of springclips of anyknown construction, the heel tip and filler or the top-lift beingpreferably located, as in the construction now being described, andillustrated more particularly in Fig. 5, just below the level of theunder surface of the heel so as to enable the tip or top-lift to beplaced in operative position beneath the attached heel without need forany raising of the latter after it has been attached to the boot, toaccommodate the thickness thereof. To enable this to be done, as shownin Figs. 2 and 5, the nail-holder L is located in its recess K at aslightly lower level than is the nail-holder M in the recess K Apreferred form of spring-clip, 5

drawings. S is a horizontal stud T, Fig. 3, free to the same inconstruction for both heel and tip, is shown in Figs. 5 and 6. It issimilar to that described in the aforesaid Letters Patent No. 694,656and comprises in each case an adjustable back-gage P, and a springcontrolled breast gage P, the shanks of the said gages working in guidesformed by plates P P respectively, screwed on to the top of the movableframe K.

The nail-holders L M may be provided with nails or slugs in anyconvenient manner by hand or mechanically. Preferably, as shown in thefigures, two nail-carriers S S are provided carried in frames each onthe end of a swinging arm S S respectively. Each arm is pivoted on asmall bracket S bolted on the machine frame. These arms with theirsupporting brackets are shown clearly in Fig. 7. The ends of the armsfarthest from the carrier frames are curved toward each other andprovided with geared segments S which intermesh, so that movement in onearm produces a corresponding movement in the other. One of the arms, sayS has a handle S by which the operator may swing the arms from thenailreceiving position shown in broken lines in Fig. 8 to thenail-delivering position shown in full lines in the same figure, and inFig. 7. The arm S is also provided with a spring catch S (shown in Fig.7) arranged to engage a detent (not shown) on its supporting bracket Sto retain the arms in the nailreceiving position.

Preferably to supply the nail-carrierblocks with nails or slugs two setsof naildelivering apparatus are provided, one on each side of themachine. These may be of any suitable construction and supported in anyconvenient manner and may be conveniently operated by a horizontal shaftS fixed in a lug on the back of the machine frame, but these form nopart of the invention and need not, therefore, be described in thisspecification.

As usual in this class of apparatus, the machine when started isarranged to run only while one complete cycle of operations of themachine is performed and then to stop automatically, that is, in themachine as herein described, after one complete revolution of the shaftJ. A suitable start and stop gear, which however forms no part of thisinvention, is provided, the gear being started by the operatordepressing the treadle T. Prefchine frame.

erably this stoppage is arranged to take place so that both of the setsof nail drivers are in inoperative position, that is, neither set is inposition between the plunger and the ack. j chine to provide mechanismwhich w1ll prevent the machine being started except when 3 the nailcarriers are in the nail-receiving po- 3 sition.

It is also usual in this class of ma- The following convenient mechanismfor this purpose is illustrated 1n the Pivoted on the nail-carrier armslide in a sleeve T fixed on the top of a vertical shaft T carried inbrackets on the ma On the lower end of the shaft T is fixed a segmentalgear T which engages a rack on a horizontal sliding rod T. The rod T iscarried in bearings in the machine frame and so arranged in relationwith the segmental gear T that when the carrier arm is moved from thenail-receiving position the rod engages wit-h an arm T, forming part ofor in fixed relatlve position to the treadle T, so as to prevent thedepression of the latter.

The operation of the machine is as follows :The stopping gear isarranged to stop the machine with the movable block K in a centralposition, as shown 1n Flgs. 2 and 3, that is, with the plunger midwaybetween the two nail-driver actuating-slides and engaging neither ofthem, both sets of nail drivers being thus away from their operativeposition under the jack. The operator having placed a shoe onthe ackswings the nail carriers by means of the handle S into theirnail-delivering position, shown in full lines in. Fig. 3, and thenreturns them, a set of nails or slugs having been delivered to eachnail-holder, to their nail-receiving position, shown in broken lines inFigs. 2 and 3. He then places a heel in the heel spring-clip over thenailholder M and a tip with its filler or a toplift in the spring-clipover the nail-holder L and depressing the treadle T starts the machine.The plunger J commences to rise, lifting the table H and with it themovable block K, and the heel. At the same time, owing to the shape ofthe cam groove I 14 the movable block K is swung toward the left hand ofthe observer, looking at Fig. 2, so that before the heel has beenbrought in actual contact with the shoe, the heel and its set ofdrivers-actuating-slide, drivers-block and nail-holder are brought intooperative position beneath the shoe and above the plunger. There is nowa dwell in the cam and the frame K consequently remains stationarv as tohorizontal movement, while the plunger still rising first presses theheel firmly against the shoe, and then raising the drivers, inserts thenails. The plunger commences to descend, and as soon as the heel, nowfixed on the shoe, is clear of its again in a central position and theplunger in its lowest position. The movements are now repeated, but withthe side movement of the movable frame reversed, the frame moving firsttoward the right hand, bring ing'the tip and its set of nailholder,drivers-block, and actuating slide beneath the shoe and over theplunger, the frame finally moving again toward the left hand, so thatthe frame is in its original central position on the completion of therevolution of the shaft J.

With reference now more particularly to Figs. 10 to 24, which illustratea convenient construction for combining the invention with aheel-attaching and top-lift-spanking machine of the kind described inthe said Letters Patent No. 694,656 :-in the machine of the classdescribed in said Letters Patent only one nail-holder and one set ofnail drivers are employed and a swing frame or plate, such as D, isprovided which carries, in jaws 7?. 7L and D 6 respectively, a heel anda top-lift, the said plate being adapted to be swung so as to place theheel and the top-lift alternately in position over the nailholder andset of drivers operated by a reciprocating plunger. The heel is firstattached, leaving the heads of the nails pro jecting beyond the same;the swing plate then oscillates and brings the top-lift under theattached heel on to which it is then spanked. To enable this to be doneby the same nail-holding-block as that which is used in the driving ofthe heel-attaching nails and by elevation of that block to the sameheight and by the same means as in the heel-attaching operation, atoggle-lever arrangement G C is provided at the back of the machine toraise the bootafter the heel is attached sufficiently to allow thetoplift to come underneath the same. In carrying out the application ofcertain features of this invention to this class of machine thefollowing changes and additions are made The nail-driving plunger isemployed in conjunction with a table and a movable frame substantiallyas in the first construction herein described, the movable frame beingpivoted on an upward extension of the table and preferably manuallyoperated by means of a handle, its operative position being governed bytwo detents attached to said handle. It is placed in the machine so thatits top surface is slightly below the level of the swinging plate Daforesaid. The tip and filler are preferably carried in a recess in aplate arranged over their nailholder, and the heel, carried in theheelholder of the swinging plate, is thus at a slightly higher level, sothat the tip and filler may be moved laterally into operative positionbeneath the attached heel without anv raising of the latter, renderingthe j ackraising movement referred to above unnecessary. Mechanism is,therefore, provided for rendering the jack-raising mechanism referred toabove inoperative when desired. The heel to be attached is carried inthe spring heel-clip provided in this class of machine on the swingingplate D, and, as this plate remains stationary While the improvedmachine is used to attach tips and fillers, mechanism is provided forthrowing out of action, when desired, the means for swinging the saidplate, leaving it in p0sition with the heel-holder over the nailplunger,during the whole cycle of operation of the machine. It is, therefore,necessary to insure that the holder leaves a free passage for the tipwhen raised by the plunger, and to prevent the spring-clip, forming partof the holder, from closing in under the heel when the heel-carryingplat-e, raised with the movable frame aforesaid, drops after the heelhas been attached, as in that case the clip would get in the way of thetip when the latter is being moved up for attachment to the heel.Mechanism is, therefore, provided for moving and holding the jaws of theholder a proper distance apart after the removal of the heel, and clearof the rising tip.

The Figs. 10 to 2 1 illustrate so much of a machine such as is shown inthe second construction described in the aforesaid Letters Patent as isnecessary for a full understanding of the additional mechanisms embodying this application of the invention. The plunger J and the table Hare preferably substantially the same as described in the firstconstruction of the machine herein set forth, as is also the arrangementin the movable frame K of the two sets of driversactuating slide andblock, and nail-holder, and the engagement with the movable frame of thehead of the plunger. WVhile resting on and being capable ofreciprocation across the table H, instead of being secured to a rockingshaft such as K, as in the said first construction, the movable frame ispivotally carried on a vertical stud I-I forming part of an upwardextension H of the table H. The movable frame has a handle K not shownin Fig. 10, by which it may be moved across the table to bring eitherthe heel or the tip nail-holder in operative position over the plunger.The handle is provided with detents K which engage catches H on thetable H to lock the movable frame in its two correct operativepositions, that is, with either the heel nail-holder or the tipnail-holder over the plunger, the normal position when the machine is atrest being with the heel nail-holder in that position, as shown in Fig.12. The movable frame is not provided, as in the first construction,with the spring-clips P P for the heel and tip. As stated above, theheel is carried in clips on the swinging plate D while the tip andfiller are carried in a suitably shaped hole in a block L shown detachedin Fig. 14: which rests on the tip nail-holder L carried in the recess Kof the movable frame K, the upper surface of the block L being on alevel with the upper surface of the said movable frame. The movableframe K is positioned in the machine beneath the swinging plate D sothat its upper surface is clear of the under surface of the plate,allowing the said frame to be swung beneath the plate. The swingingplate D, upon which is supported the heelholder h 12, and top-liftcarrier D e, is substantially similar to that disclosed in the secondconstruction of machine described in the before-mentioned Letters PatentNo. 694,656. Instead however of being mounted on a stud in thenail-block head the plate is mounted, for a purpose hereinafter fullyexplained, on a pin H eccentrically carried in a bush H mounted in abearing carried on the head of the vertical stud H which, as beforedescribed, forms part of the upward extension H of the table H. In thesaid Letters Patent the movements of the swinging plate D are operatedand controlled in the following manner :The nail carrier 0, whichdelivers the nails to the heel nail-holder, is carried on an arm C freeto turn on a stud C on the machine frame and having a handle (not shown)and a spring catch (not shown) which retains the carrier in its normalnail-receiving position until removed therefrom by the operator. On thelower end of a stud c on the carrier arm is a jointed actuator or cam dformed of two parts united by a pin and spring, so as to permit the freeend of the actuator to be turned down when required. The free end of theactuator is curved, and in the movement of the nail carrier arm C fromthe nail-receiving position into the nail-delivering position said endmeets a roller (Z said roller being mounted on a stud 10 extendingdownwardly from the swinging plate D and swings the plate into positionwith the heelholder over the nail-driving plunger. The stud 10 is cutaway on one side below the roller d, and whenever the plate D is inposition so that a heel carried thereby is over the plunger ready to beattached, the stud is caught by one arm of a spring-controlled lockingdevice or detent 6 having a tail (Z and pivoted at d on an adjustableblock (Z To release the stud 10 a trip or releasing device 18 is pivotedon one side of an arm Y secured on to a portion of the main frame and isheld by a spring 17 above the tail d of the detent, so that as thedetent rises with the plate 1), its tail Z engages a notch on the trip18 and raising the latter, passes above it. On the following descent ofthe plate D the tail (Z engages an inclined surface on the trip 18, andthe detent is turned, releasing the stud 10, allowing the said plate tobe swung by a spring-controlled rod f into position with the top-liftover the nail-driving plunger.

For the purposes of the present invention the following mechanism may beprovided to place and to hold the trip 18 when desired out of action :Afiat spring Y is fixed at one end on to the opposite side of the arm Yto that on which the trip 1.8 is pivoted. The free end of the spring isprovided with a pin Y engaged in a hole bored through the arm Y and sopositioned that when the trip 18 is in its lower position as shown inFig. 18, the pin is pressed by the spring Y" against the side of thetrip. V hen the trip is raised by the detent, as above described, itpasses above the pin Y which, under the pressure of its spring Y, unlessprevented by a device as hereinafter described, is protruded in the pathof the trip, preventing its falling under the action of the spring 17and retaining it in the position shown in Fig. 20 out of engagement withthe tail (Z of the detent, during any subsequent upward or downwardmovement of the same. The detent is consequently not turned on itsdownward movement and retains the plate D in fixed position. To enablethe operator to throw the pin Y out of operation, when it is desired tospank on a top-lift and allow the plate D to be swung for this purpose,a handle Y may be pivoted on the trip-carrying arm Y The handle Y isprovided with an arm Y hav ing a wedge-shaped end Y adapted to engage,when the handle is in a vertical position, between the spring Y and thearm Y on which it is carried, so as to draw back the pin Y from the pathof motion of the trip 18 into the position shown in Fig. 17 so that theplate D may be swung at the normal period in the cycle of operation ofthe machine.

As before stated, the heel is held in the holder or spring-clip on theswinging plate D. This holder comprises a guideway plate 6, arranged toreceive the shanks respectively of the breast-gage 7L and the back-gageif. The breast-gage is provided with a suitable spring h which actsnormally to keep the breast-gage in contact with the breast of the heel.The back-gage h is normally stationary on the plate, but has to becapable of adjustment as described and illustrated in the aforesaidLetters Patent to adapt it to heels of different sizes, this ad justingdevice being omitted from the drawings accompanying this specificationfor the sake of clearness. It is necessary to prevent the breast-gage hfrom closing in under the heel when the swinging plate D, raised withthe movable frame K and table H, drops after the heel has been attached,as in that case it would get in the way between the tip and the attachedheel when the tip is being moved up for attachment to the same; it isalso advisable to move the back-gage to insure the allowance ofclearance for the tip. To move the back-gage k and to secure theautomatic opening of the breast-gage h the following mechanisms may beprovided :As above stated, the plate D for the purpose of this inventionis mounted on pin H eccentrically carried in a bush H on which pin theplate swings in the normal operation of the machine, in the mannerdescribed in said Letters Patent No. 694,656 before referred to. Thebush H has attached to its lower end a gear pinion H,, which is engagedby a segment gear K formed on or attached to the movable frame K, thegear being so positioned relatively to the pinion that as the frame K ismoved, after a heel has been attached, to place the tip and filler inposition over the plunger the gear actuates the pinion and its attachedbush to move the pin H and with it the swing plate D and the back-gage7L backward. Simultaneously with this a roller stop I 19 on the movableframe (see Figs. 12 and 13) engages with a striking piece H on a smallslide H (see Figs. 21 and 22) on the under side of the said swing plate.The slide H carries an upwardly extending detent or pawl H which engageswith ratchet teeth H formed on the under surface of the shank of thespring-controlled breast-gage it, so that as the movable frame K isactuated the breast-gage or clip h is thereby swung forward toward theoperator and clear of the heel. A spring I 11 draws back the slide toits normal position when the striking piece is released by the returnmovement of the movable-frame. The hole in the plate D through which thepawl extends to engage the teeth H is so shaped that when the slide isin its normal position, that is, out of engagement with the roller K thepawl abuts against the edge of the said hole and is held out ofengagement with the teeth, thus leaving the breast-gage h under thenormal control of its spring 7?.

In said Letters Patent No. 694,656 thejack is raised to enable thetop-lift to be placed under an attached heel in a known manner by meansof a walking beam and its attached toggle C C actuated by means of apendulum lever and operative connections (not shown) with thenail-driving plunger in a well known manner, so as to depress the jackfor the attachment of the body of the heel, and then to raise the samesufliciently to permit the after attachment of the toplift. As beforestated, when the movable block is employed to attach a tip and filler,this movement of the jack is not required and the following is aconvenient device for holding the ack stationary when desired As shownin Figs. 23 and 2%, a wedge W is provided on the end of a curved arm Wpivoted in a boss VW on the machine frame and provided with a handle V1the wedge and arm being so positioned that by turning the arm on itspivot the wedge may be placed, as shown in full lines in Fig. 24,between the toggle C C and the machine frame, thus preventing thebreaking of the toggle and consequent raising of the jack. As shown inFig. 28, the wedge may be conveniently carried in horizontal guides Asshown in Figs. 12 and 13 the frame K may be provided with a cover plateL pivoted at L on a stud on the frame K, so to be swung over the heeltip and filler, when the same has been placed in position in the frame,to prevent vibration engendered by the movements of the said framejerking the nails up out of the nail-carrying block.

When the frame K is swung over to place the tip in operative positionover the plunger an abutment L on the cover plate is engaged by theswinging plate D so that the cover plate does not move with the frame Kunder the heel, but is held back on its pivot as the tip moves intooperative position.

When it is desired to use the machine to nail on a heel and then spankon a top-lift in the manner described in said Letters Patent No.69%,656, the operator locks the movable frame K in the position shown inFigs. 11 and 12, withdraws the wedge W from the position shown in fulllines in Figs. 23 and 24 into the position shown in broken lines in Fig.24, allowing the jack to be raised and lowered by the action of thetoggle C C and by means of the handle Y places the wedge-shaped end Y*of the arm Y in the position shown in Figs. 17 and 18, permitting thetrip 18 to act and the plate D to swing after a heel has been attached.The machine is then operated as described in the patent referred toabove. lVhen, however, it is desired to nail on a heel and then nail ona tip and filler, or secure a top-lift with slugs, the operator reversesthe position of the wedge 1V and handle Y, thereby locking thejack-raising toggle and the plate D, and after the heel has beenattached places the tip and filler or the toplift in position over theplunger by swinging the movable frame K into the position shown in Fig.13.
